High quality InSb and InSbN alloys were grown epitaxially on InSb (100) by metal-organic chemical vapor deposition. Low temperature photoluminescence spectra of InSb epilayers revealed that in addition to the main band-to-band emission around 5.4 μm, an emission peak around 5.87 μm was also be observed. Our results indicate that the low energy emission peak was originated from the antisite SbIn defects...
Indium antimonide (InSb) has the highest electron mobility and saturation velocity of any conventional semiconductor, giving potential for a range of analogue and digital ultra-high speed, low power dissipation applications. N-channel quantum well FETs have been fabricated with current gain cut-off frequency (fT) of more than 250 GHz and power gain cut-off frequency (fmax) of 500 GHz. Outline designs...
Indium antimonide has the highest electron mobility and saturation velocity of any semiconductor, so has potential for ultra-high frequency operation with very low power dissipation. Unoptimised, uncooled quantum well heterojunction FETs, with gate length of 85nm, that have a cutoff frequency of 340GHz at only 0.5 V Vds. The prospects of this technology for future microwave applications in excess...
